Erieau ridge is a glacial moraine that crosses into Lake Erie near Erieau, Ontario and Pointe aux Pins.[1][2]
The ridge may be the offshore extension of the Blenheim moraine.[3]

Pointe aux Pins may have initially formed opposite the moraines of Erieau Ridge, located just inland from the point, and slowly migrated northeastward along the shore.

The Erieau Ridge is capped by glacial drift and is interpreted as a segment of a morainic ridge.

The Erieau Ridge aligns with, but is not topographically continuous with, a very low (less than 1 m relief) almost buried ridge extending northward from Cleveland to a point about half way across the Lake (plate 1A). Cores penetrating the overlying postglacial mud on these two aligning ridge segments, which were given the name Erieau-Cleveland Ridge by Lewis, et al. (1966), encountered sorted sand. This Ridge has been interpreted as the remaining trace of an end moraine extending across the Lake (Sly and Lewis, 1972; Coakley, 1992).
